Protobuf.net How to use the Any data type?

I have seen example *.proto files where a google.protobuf.Any data type is used. E.g. from the Eclipse Tahu Sparkplug Version B specification where there is something like:

Excellent question. I've been meaning to address this area for ages. The answer is a simple "no, I haven't even looked at it". I'd be happy to do so, but reality is that I have limited time and need to prioritise effort on features people are asking for. "Any" is something I've heard basically no noise about, until today. If you have a genuine use case for it, we can probably look. GitHub or email may be a better place to explore it, unless you're happy to handle it simply via byte[] and your own code.

How to retrieve any keys in dictionary of composite values by a single value

I'm coding a program that will print output on what is happening with parts of an internal combustion engine. I have an abstract class called CarSystemParts that all car part classes inherit from.

I have a Dictionary> that shows which classes should be affected or physically pushed by other parts. It's defined like this:

I think you can solve your problem using Where to filter the elements you want, then Select to only keep the Keys.

QUESTION

How is the Sparkplug is_historical metric property used?

Asked 2019-Jun-18 at 23:15

I am reading through the MQTT Sparkplug spec, and I've come across the is_historical property of a metric. The doc explains that it prevents updating of real-time tag values, but I've been unable to find any indication of the use case(s) that led to the inclusion of the property. Is it perhaps to allow SCADA systems to ignore alarm conditions in historical values?

...

ANSWER

Answered 2019-Jun-18 at 23:15

The is_historical property is used to flag a Metric as a historical value or change event. The most common use case for this would be when an edge application goes offline for a period of time and stores all the data change events locally. When the application comes back online and publishes the stored values, it can set the is_historical property to let the consuming application know that it is not a live value. The consuming application could then use the is_historical property to handle the data appropriately. Your suggestion of ignoring alarm conditions is a good example. The application could also decide to store the event directly in a historical database, bypassing any live displays.

QUESTION

What is the difference between Bdseq and Seq number in MQTT Sparkplug

Asked 2019-Jun-18 at 22:36

I am using C# Sparkplug library and trying to publish data. I need a clarification about BdSeq number and message Seq number.

Should we use only one variable for seq and BdSeq number? Start at 0 and increment till 255 when publishing NBIRTH, DBIRTH, NDATA and DDATA?

what is the difference between BdSeq number and message Seq number.

Also, I have seen the metric for Bdseqnum takes a datatype of UInt64 in the document. If the limit is only till 255, why are we using UInt64?

Thanks.

The bdSeq number and the seq number have different uses and should not share the same variable.

The seq number should be part of every DBIRTH/NBIRTH/DDATA/NDATA/DDEATH message. It is used to ensure in-order delivery of the messages to any consumer of the data.

The bdSeq is used to track the overall session of the Sparkplug client. It is a number is a special Metric that is only present in the NBIRTH/NDEATH messages. It is used to match a NDEATH (published by the MQTT Server on behalf of a disconnected Sparkplug client) with a previously published NBIRTH message. The consumers of the data use the NDEATH to know that the Sparkplug client is offline. The reason this is necessary is because it is possible that a Sparkplug client might lose their connection, reconnect, and publish a new NBIRTH before the MQTT Server publishes the NDEATH from the previous session. In this case the new NBIRTH will contain a new bdSeq number and any subsequent NDEATH messages with old bdSeq numbers can be ignored.

QUESTION

Listbox population sometimes shows number instead of text value

Asked 2018-Jun-18 at 18:32

I have a listbox in a userform. I use a SQL query to pull data and then populate the listbox. When I look at the query in SQL, it is fine and shows text in those fields. The listbox is showing these numbers though, 4 and 5, what I am assuming is the column name or fields value?

It should say "Landfill/Wellfield" and "O2 levels", so it is not a text length issue. This is all test data. The last column correctly shows "Sparkplugs/Ignition System"

The listbox has 7 columns of data.

Code for the listbox population:

ANSWER

Answered 2018-Jun-18 at 18:32

I figured it out, I am not sure what the issue was, but using this to populate the listbox instead of the above does not cause the issue. I've used that first code all the time before so it might be a Fields() issue or something. See below:
